<p>PURPOSE:To surely make the resistance value of a metal film resistor uniform without peeling the terminal electrode of the resistor by spirally trimming a metal resistance film on a blank, and then forming the electrodes at both ends of the blank. CONSTITUTION:A metal resistance film 2 is formed on a resistor blank 1, and the film 2 formed on the blank 1 is spirally trimmed at 4 thereby to regulate its resistance value. In this case, after the film 2 formed on the periphery of the blank 1 is spirally trimmed at 4 while measuring a resistance value between contact terminals 3 and 3' in contact with the film 2 on the end face of the blank 1, terminal electrodes 6, 6' are formed on both ends of the blank 1. As a result, the electrodes 6, 6' are not peeled by chucking or handling in case of a step of trimming 4, and an accurate resistance value can be regulated.</p> |
